JOSEPH S. BOHATKA, OF CHICAGO, ILLINOIS.

SWING.

Specification of Letters Patent.

Patented May21, 1912.

Application filed March 1, 1912. Serial No. 680,796.

To all whom it'may concern:

Be it known that I, J osnrrr S. BOI-IA'LKA, a citizen of the UnitedStates, residing at Chicago, in the county of Cook, State of Illinois,have invented certain new and useful Improvements in Swings, of whichthe following is a specification, reference being had to theaccompanying drawing.

My invent-ion relates to swings of the class adapted to be supportedbetween door-posts or other oppositely-disposed uprights, the swing andits supports being adapted to be entirely removed whenever desired.

It is the object of the invention to provide removable supporting meansfor swings of this type which will be held securely in place whenever itis in use and which may be readily removed and as readily placed inposition.

It is a further object of my invention to provide supporting means ofthis sort which may be folded compactly for storing when not in use.

It is a further object of this invention to improve swings of this typein sundry details hereinafter pointed out.

The means by which I have accomplished these objects are illustrated inthe accompanying drawing and hereinafter specifically described.

That which I believe to be new is set forth in the claims.

The drawing is a view of a device embodying my improvements in positionin a door-way, one of the pivoted bearing shoes being shown partly insection.

Referring to the drawing, 10 11 indicate door-posts, between which thesupporting device is positioned.

1213-1 115 indicate levers, preferably in the form of metal bars, allmounted upon a suitable pivot-pin 16 so as to be capable of swingingrelative to each other.

17 indicates shoes of any suitable type pivotally mounted upon the outerends of the levers, each of the shoes in the construction shown beingprovided with a facing 18 of rubber or other suitable material.

19 indicates a spring tending to draw toward each other the levers lb-15, and 20 indicates a spring tending to draw toward each other thelever 1213.

21 indicates a cord or rope passing loosely through an opening in theshort arm of the lever 13 and secured to the short arm of the lever 12by means of clips or in any other suitable manner.

22 indicates a cord or rope passing loosely through an opening in theshort arm of the lever 15 and secured to the short arm of the lever 14by means of clips or in any other siutable manner.

23 indicates a clip of any suitable type carried by the lever 13 throughwhich the rope 22 passes, and 24 indicates a similar clip carried by thelever 15 for the rope 21.

25 indicates a swing of any suitable type suspended from the ropes 2122.

.As will be readily understood, when the supporting device is placed inposition between two oppositely-disposed uprights, the shoes 17 beardirectly upon such uprights, the springs 1920 tending to force thelevers at each side toward each other and consequently tending to forcethe shoes 17 at one side farther laterally from the shoes 17 at theother side. The force of the springs 19-20 exerted in this manner issuflicient to hold the device in position, the rubber facings of theshoes 17 enabling such shoes to effect a secure hold upon thedoor-posts. l/vhenever, with the parts in the positions shown, a childplaces its weight in the swing, the downward pull on the ropes 21-22tends to draw the levers together at both sides, thus holding thesupporting device firmly in position between the uprights.

W'henever it is desired to put the swing aside for the time being, thiscan be accomplished readily by merely forcing the levers apart at eitherside against the action of the springs 1920, when the supporting devicecan be folded together into a compact bundle and hidden away in anyconvenient place until it is wanted again.

It will be understood, of course, that my improved swing support may beused in door-ways of various widths, the springs 19-20 permitting thespreading of the levers apart to fit door-ways narrower than that shownin the drawing, and such springs serving to draw the levers closertogether at the sides to fit door-ways wider than that shown.

What I claim as my invention and desire to secure by Letters Patent is,

1. In a swing support, the combination of four levers pivotally mountedrelative to each other, two of which levers extend in one direction andtwo of which extend in the opposite direction to engageoppositely-disposed uprights, and a rope at each side connecting theshort arms of said levers whereby a downward pull upon said ropes tendsto draw the levers together at each side.

2. In a swing support, the combination of four levers pivotally mountedon a horizontal axis, the longer arm of each of which levers bears uponone of two oppositely-disposed uprights, and a rope at each sideconnected to the lower short arm at that side and passing through asuitable opening in the upper short arm at that side, whereby a downwardpull upon said ropes tends to draw the levers at each side together.

3. In a swing support, the combination of four levers pivotally mountedrelative to each other, shoes pivotally mounted on the arms of two ofsaid levers extending in one direction, shoes pivotally mounted on thearms of the other two of said levers extending in the opposite directionwhereby said shoes are adapted to bear upon oppositelydisposed uprights,springs connecting said levers tending to draw together the shoes ateach side, and a rope at each side connecting the short arms of saidlevers whereby a downward pull upon said ropes tends to draw the loverstogether at each side.
